j Application filed man same, Serial n 90,962.

This invention relatesto an attachmentto be employed in connection with a well known type of vehicle, the zprimar y'object'f of the invention being to; provide 'means whereby the clutch pedal maybe held against movement'when" it has been forced'into' a position-to throw the low gear otthevvehicle, into operation."

An important object of the inventionlis to provide a'device of this character which will be automatic in its operation, and one which may be thrown out of use with the I minimum amount of exertion on thepart of the operator: V 7 r. V I

A still further object of theinvention' 1s .to provide a clutch pedal lockllwhich may e be readily and easily attached to theusual motor vehicle construction, eliminating: the

necessity of making alterations in the-usual construction to install the device.

With the foregoing and other. Objects in view which will appear as the description proceeds, the invention resides insthe com bination and arrangement 'ofpartsand in the details of construction hereinafter described and claimed, it b-eing'understoodthat changes'in the precisev embodiment of the invention herein disclosed, may be madev 7 within the scope of whatis claimed, w1th- 30 out departing from the spirit of the 1I1V811-1 transmission cover that is bolted to the hous ing 6 by means of the bolts 7 arranged at f the corners of'the housing and at points adjacent to the edges of the cover. 7 a

The device forming the essence of the invention includes an arm 8 which is bolted to the transmission, housing by means of bolts 9, the usual bolts 7 arranged intermediate the ends of the transmission cover have in been removed and replaced by the bolts 8.

' The arm 8 is substantially long so that one i end thereof extends beyond one side of the transmission housing where the same is bent by Figure 3.
